Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.

Referring to FIG. 2 and FIG. 3, a first embodiment of the connecting device 2 of the present invention comprises a frame 3 of a plurality of docking arrangements, and a plurality of combining units 4 respectively combining two adjacent frames 3. The following text and drawings are illustrated and drawn by two adjacent frames 3 and a combining unit 4 combined with the frames 3 for ease of explanation. Each of the frames 3 includes a base wall portion 31, two extending wall portions 32 respectively extending from the base wall portion 31 and spaced apart from each other, and two limiting portions 33 respectively formed on the extending wall portions 32. The base wall portion 31 and the extension wall portions 32 cooperate to form an inverted U-shape and surround a space 34. The frames 3 are aligned to form the base wall portion 31 and the extension wall portion of the frames 3. The 32 are aligned with one another and the spaces 34 of the frames 3 are interconnected. The limit 33 is located in the space 34 and faces each other, and each of the limiting portions 33 has a first fixing portion 331 disposed on the corresponding extending wall portion 32, and is disposed on the extending wall portion 32 and adjacent to the first portion The second fixing section 332 of the fixing section 331 is an angle of the first fixing section 331 and the second fixing section 332 as shown in FIG.

Each of the combining units 4 is located in the spaces 34 of the two adjacent frames 3, and includes a fixing elastic piece 41, and two adjusting members 42 that are spaced apart from each other and that are inserted through the fixing elastic pieces 41 and respectively abut against the two frames 3. . The fixing elastic piece 41 has a single body portion 411, and the two clamping portions 411 are spaced apart from each other and extend obliquely, and are respectively engaged with the first fixing portion 331 and the second fixing portion 332 of the limiting portions 33. Part 412. In the first embodiment, the adjusting member 42 is a screw, and the body portion 411 is provided with two screw holes B respectively for the adjusting members 42 to be screwed (FIG. 3 shows only one of them due to the viewing angle) . Each of the adjusting members 42 passes through the sheet portion 411 and the end touches the base wall portion 31 of the corresponding frame 3.

When any of the adjusting members 42 is rotated, the adjusting member 42 should be moved relative to the sheet body portion 411 toward the base wall portion 31 of the corresponding frame 3, but since the end of the adjusting member 42 is as shown in FIG. The ground portion abuts against the base wall portion 31, so that the adjusting member 42 is blocked and cannot move in this direction, so that the sheet portion 411 which is not restrictedly moved and screwed by the adjusting member 42 is shown by a broken line in FIG. Moving away from the base wall portion 31, the sheet portion 411 generates an axial force away from the base portion 31, and drives the sheet portion 411 of the fixed elastic piece 41 to be deformed. When the fixing elastic piece 41 is deformed, the card of the fixed elastic piece 41 is placed as shown in the force diagram of FIG. The portion 412 simultaneously applies a pressing force in the direction of the two extending wall portions 32 of the two adjacent frames 3, thereby joining the two frames 3 together to achieve the function of the fixed card.

When the adjusting member 42 is rotated, the fixing elastic piece 41 is fixed. The component force diagram is still as shown in FIG. 4, and the adjusting member 42 moves relative to the base wall portion 31 of the frame 3, and pushes the sheet body portion 411 to move the sheet portion 411 away from the base wall portion 31. Further, the sheet portion 411 is concavely deformed and the pressing portions 412 are biased toward the extending wall portion 32 of the frame 3 to achieve the bonding effect. This second embodiment provides another configuration that increases the versatility of the present invention.

Referring to FIG. 6, a third embodiment of the connecting device 2 of the present invention is different from the first embodiment in that each frame 3 further includes a space 34 spaced apart from the base wall portion 31 and disposed in parallel with the base portion 31. The retaining wall portion 35 of the extending wall portion 32 is connected to the inside. The base wall portion 31 and the barrier wall portion 35, And the extension wall portion 32 defines a region 36, and the fixing elastic piece 41 of the coupling unit 4 is located in the regions 36 of the two adjacent frames 3. Each of the limiting portions 33 is formed in the region 36 and is in contact with the corresponding latching portion 412 of the fixed elastic piece 41. Each of the retaining wall portions 35 defines a screw hole D. The adjusting members 42 are respectively threaded through the screw holes D of the corresponding blocking wall portion 35, and the end portions abut against the body portion 411 of the fixing elastic piece 41. When any of the adjusting members 42 is rotated, the adjusting member 42 moves toward the sheet portion 411 with respect to the blocking wall portion 35, and simultaneously pushes the sheet portion 411 toward the base portion 31 to deform. The force-distributing force of the fixing elastic piece 41 is as shown in FIG. 7 , so that the locking portions 412 of the fixing elastic piece 41 will exert an urging force on the limiting portions 33 outward in the direction of the extending wall portions 32. Thereby achieving a fixed effect. This third embodiment provides another configuration to enhance the versatility of the present invention.

Referring to FIG. 8 and FIG. 9 , a fourth embodiment of the connecting device 2 of the present invention is used for applying the connecting device 2 to a light fixture 5 . The light fixture 5 includes the foregoing connecting device 2 , and a plurality of the connecting devices 2 are respectively disposed on the frame 3 . The light source 51 in the space 34 (only one of which is shown in Figure 9 due to the viewing angle of view). When the luminaire 5 is assembled, a combination unit 4 is firstly placed on one of the frames 3 as shown in FIG. 9, and then the other frame 3 is docked, so that the fixed elastic piece 41 is a card as shown in FIG. The adjusting members 42 are placed in the spaces 34 of the two frames 3 to deform the fixing elastic pieces 41 to fix the two frames 3. Through the docking structure, the lamp 5 can be freely expanded according to requirements, has a simple structure and is convenient for modular production, and is easy to disassemble and easy to change configuration or maintenance.
